    Brickshelf no longer allows hosting PDF files, so that 3 year old link is dead now. You can now get the instructions at MOCPlans.

    Not so! Airplanes have had mechanical ratio changers for years. For example, on some commercial aircraft the ratio between the movement of the rudder pedals and the movement of the rudder itself is a function of airspeed. This is to prevent too much rudder motion at high speed. The system is entirely mechanical and based on dynamic air pressure. For a vehicle like this, I can imagine some kind of flywheel that changes the gear ratio to the tilt as a function of wheel speed.

    Most Eurobricks users do not upload their pictures directly to Eurobricks. As you have noticed, the upload limit makes that almost impossible. In most cases, people use an image hosting service such as Flickr or Bricksafe (recommended). You can post as much as you want there, and then just link to the photos in your post.

    I've made a few corrections to both the parts list file and the CAD file that I posted. For anyone using my files, the corrections were to a couple of parts it the submodel "Cab.ldr" and the doors of the cab "Door6.ldr" and "Door7.ldr". For a model of this size and aspect ratio, you will need to use landscape orientation as suggested by afol1969. When trying to zoom in on a model, you are going to run into an LPub bug that I discovered and discussed in the LDraw forum here. I recommend you read the thread because it will save you a lot of time. Basically, when zooming in LPub won't let you translate the model to be looking at anything other than the center of the image. This is a big problem because, for instance, you will need to be able to zoom in on the front of the truck to work on the cabin. There is a workaround discussed at the link which I used for Dikkie's tow truck instructions, but it is painful. See below for an example of how it finally came out. By the way, I also have pre-made files that I use for parts list images of LEDs, pneumatic tubes, and extension wires. If you'd like to use them for the instructions, let me know.

    The link is further up in this thread. Buy the instructions at crowkillers.com.

    If it had PF, it wouldn't be Grazi's tow truck. ;). I'm not sure that this conversion would buy you anything. His truck is all studded so the old motors integrate much better. Most functions are pneumatic anyway. Converting them to LAs would defeat the whole design of the truck.

    I extracted a Brickstore inventory from the CAD file and compared it with the previous inventory I had made manually from Madoca's photos. They differed by about 20 parts after I corrected a couple of issues in the CAD file, so at this point I consider the Brickstore inventory as accurate as it is going to get until someone builds the model.

    I've posted the CAD file to my Bricksafe account. Feel free to use it for whatever you like.

    I am not suggesting buying another set, I am suggesting buying just a box. You can search for boxes and instructions independently. I think it will be hard to find an available box for a set this old though. Many of my old boxes are also issuing the clear cover.

    Finished the CAD file late last night. There are some really weird angles in the roof and windshield, so it was a challenge.

    Today I drew a box. Doesn't sound very impressive, but it is a very nice box. To put it in perspective, there are 1731 parts in the box compared with 1838 in the entire motorized chassis. With this complete, all I have left to do is the cab. According to LDView, I've got 3611 parts in it so far. When I'm done, I'll compare the parts list from the CAD to the one I already generated from Madoca's photos. It will be interesting to see how close I got. This thing is really enormous. I checked the bouding box in LDView and the total length of this monster is 1807 LDraw units or 90 studs. By way of comparison, Dikkie Klijn's huge tow truck is 105 studs and Designer Han's 10x4 dump truck is 67 studs. I enjoy "virtual building", but I do not enjoy the wire synthesizing. After doing the 100+ wires and tubes in Dikkie's tow truck, I swore I would never put that much work into a CAD file again. So someone else will have to volunteer for that part!

    I doubt you will be able to find that separately. You might end up having to buy a whole box off Bricklink.

    It is not for sale, but you can come and dust it for me.

    Sorry if I have ruffled any feathers. I didn't mention it because mine is an independent project. This CAD file is not for building instructions, It has no proper steps and does not have proper submodels for building. I just enjoy virtually building it while I am waiting for the parts to arrive. It gives me a chance to see how things go together and I love figuring out how things work. The project by the rest of you to make instructions should absolutely keep going! Of course anyone is welcome to use any part of my file if you like.

    I couldn't help myself: When I am finished with the CAD, I will be curious to see how this would look with an all gray chassis instead of red. I think the red clashes with the rest of the truck a bit. Of course, I have already collected all the chassis parts in red so I'll have to build it that way.

    I'm moving this thread to the "General Discussion" forum since it is not related to Technic.

    The wheels are free-spinning during shift, however the duration of the shift event is longer than it takes for the vehicle to lose its momentum. This is due to a combination of low speed and friction. If the vehicle was travelling much faster (or down a hill), you would see that it is possible for it to continue moving during the shift. They can't . AAA batteries have much lower current capacity than AA even though the voltage is the same. However, the AAA box is also much lighter. If you have a very, very light MOC such that the battery box is a significant portion of the total vehicle weight, the loss of weight might be more important than the loss of current. However, in most cases the AA box will perform much better.

    GuiliuG has designed exactly such a loader. It can switch between 4 wheel steer and skid steer. It is much larger, more complicated, and more expensive though. You can read all about it in another thread. The vast majority of real skidders do not have this capability though. The whole point of making skid steer in the first place is that it is dead simple.

    No, we all thought the same of you before your entry, so no change.

    I stopped at my local Lego store today to get a Power Functions expansion set, and I was amazed to see a 41999 sitting on the shelf so I bought it immediately. I can't believe they had one! They told me it just randomly arrived in their latest shipment. So that proves there are still some in circulation.

    I owned a couple of them briefly and then later sold them because I wasn't interested. They are kind of fun, but are very basic compared with any Mindstorms stuff, and of course the software is virtually impossible to use with a modern computer. You can't even build the models without the software because there are no printed building instructions. There are a few parts in unique colors though. For example, a few thin liftarms, links, and suspension parts come in pearl here and only here. RoscoPC uses some of them for his F1 cars.

    I was hoping someone would say that! I'll be watching this space for the CAD file.

    I don't think it is off-topic. The discussion is about a potential error in Technicopedia, so it makes sense to explore the solution here. Just from a logical point of view, it makes sense for the tow truck to be part of 1981 because it goes with the buggy and was often pictured towing it. On the other hand, all of the sets from 1982 were universal sets, so it would seem out of place there. To be honest, I don't remember where I got my original information when I wrote that page. According to my revision log, I wrote those sections in December of 2009 which is before Brickset was active or the guide book was released.

    I highly recommend using Brickstore. ReBrickable will export to a Brickstore parts list which will show you all the parts, colors, quantities, and prices. You can then decide what you need and export to a Bricklink wanted list.
